Shawn	f6d3a3546f	community[patch]: document_loaders: modified athena key logic to handle s3 uris without a prefix (#17526 ) https://github.com/langchain-ai/langchain/issues/17525 ### Example Code ```python from langchain_community.document_loaders.athena import AthenaLoader database_name = "database" s3_output_path = "s3://bucket-no-prefix" query="""SELECT CAST(extract(hour FROM current_timestamp) AS INTEGER) AS current_hour, CAST(extract(minute FROM current_timestamp) AS INTEGER) AS current_minute, CAST(extract(second FROM current_timestamp) AS INTEGER) AS current_second; """ profile_name = "AdministratorAccess" loader = AthenaLoader( query=query, database=database_name, s3_output_uri=s3_output_path, profile_name=profile_name, ) documents = loader.load() print(documents) ``` ### Error Message and Stack Trace (if applicable) NoSuchKey: An error occurred (NoSuchKey) when calling the GetObject operation: The specified key does not exist ### Description Athena Loader errors when result s3 bucket uri has no prefix. The Loader instance call results in a "NoSuchKey: An error occurred (NoSuchKey) when calling the GetObject operation: The specified key does not exist." error. If s3_output_path contains a prefix like: ```python s3_output_path = "s3://bucket-with-prefix/prefix" ``` Execution works without an error. ## Suggested solution Modify: ```python key = "/".join(tokens[1:]) + "/" + query_execution_id + ".csv" ``` to ```python key = "/".join(tokens[1:]) + ("/" if tokens[1:] else "") + query_execution_id + ".csv" ``` `9e8a3fc4ff/libs/community/langchain_community/document_loaders/athena.py (L128)` ### System Info System Information ------------------ > OS: Darwin > OS Version: Darwin Kernel Version 22.6.0: Fri Sep 15 13:41:30 PDT 2023; root:xnu-8796.141.3.700.8~1/RELEASE_ARM64_T8103 > Python Version: 3.9.9 (main, Jan 9 2023, 11:42:03) [Clang 14.0.0 (clang-1400.0.29.102)] Package Information ------------------- > langchain_core: 0.1.23 > langchain: 0.1.7 > langchain_community: 0.0.20 > langsmith: 0.0.87 > langchain_openai: 0.0.6 > langchainhub: 0.1.14 Packages not installed (Not Necessarily a Problem) -------------------------------------------------- The following packages were not found: > langgraph > langserve --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	6 months ago

Kate Silverstein	0bc4a9b3fc	community[minor]: Adds Llamafile as an LLM (#17431 ) * Description: Adds a simple LLM implementation for interacting with [llamafile](https://github.com/Mozilla-Ocho/llamafile)-based models. * Dependencies: N/A * Issue: N/A Detail [llamafile](https://github.com/Mozilla-Ocho/llamafile) lets you run LLMs locally from a single file on most computers without installing any dependencies. To use the llamafile LLM implementation, the user needs to: 1. Download a llamafile e.g. https://huggingface.co/jartine/TinyLlama-1.1B-Chat-v1.0-GGUF/resolve/main/TinyLlama-1.1B-Chat-v1.0.Q5_K_M.llamafile?download=true 2. Make the file executable. 3. Run the llamafile in 'server mode'. (All llamafiles come packaged with a lightweight server; by default, the server listens at `http://localhost:8080`.) ```bash wget https://url/of/model.llamafile chmod +x model.llamafile ./model.llamafile --server --nobrowser ``` Now, the user can invoke the LLM via the LangChain client: ```python from langchain_community.llms.llamafile import Llamafile llm = Llamafile() llm.invoke("Tell me a joke.") ```	6 months ago
